PILOT-LIGHT. a

Specification of Letters Patent.

Application filed July 1, 1909.

Patented J line 18, 1912. Serial No. 505,452:

To all whom 'it may concern:

Be it known that I, GEORGE GILOHER, a citizen of the United States of America, and a resident of Ridgefield Park, New Jersey, have invented a new and useful Improvement in Pilot-Lights, which improvement is fully set forth in the following specification.

My invention relates to pilot-lights for gas-cocks.

It is an improvement upon the construction set forth in U. S. Letters-Patent No. 912,304, granted to me Feb. 16, 1909, for a device that may be changed from an ordinary gas-cock to a pilot-light, and vice versa. The object of the present invention is to improve, simplify and cheapen the construction shown inmy previous patent.

The invention will be best understood by reference to the annexed drawings that illustrate a preferred embodiment, of which- Figure 1 is a side view partly in section; and Fig. 2 is an end view, through line IIII of Fig. 1.

In the drawings, 11 represents the ordinary gas-pipe, and 2 the barrel or chamher, in which the gas-cock is mounted in the usual manner. This barrel 2 is cut away at 8, and on either side of the cut-away portion is provided with the two oppositelydisposed wings or flanges 4-4:, in each of which is mounted an adjustable screw 5.

6 is the gas-cock or stopper that is secured in the barrel 2 in the usual manner, and its interior construction being of the usual type need not be shown. Transversely through the body portion of this cock is the (diagonal) slot 7, which is more or less elongated in the direction of the axis of the cock. From the side of the stopper 6 that is opposite the cut-away portion 3, from either side of the lower end of slot 7 (which is farthest from the cutaway portion 3) are the two projections 8 that furnish a bearing in which is pivoted, at 9, a transverse lever. One end 10 of this lever serves as a handle or thumb-piece, and the other end protrudes through the slot 7 to present the nose 11 for limiting the axial turning of the cock. Suflicient tension or friction is applied upon the pivot 9 (as by a clamp-nut or the like) to cause the lever to remain in whatever position it may be placed.

The location and arrangement of the v transverse slot 7 and its lever with relation to the wings 4 and set-screws 5 is such that when the nose 11 of the lever is in its lowermost position, as shown in Fig. 1, it will not be in line with the set-screws 5 but (when cock 6 is turned) will pass beneath the same and abut against one of the shoulders 4; whereas, when the nose 11 is in its uppermost position, as indicated in Fig. 2,

it will. abut against one of the set-screws 5] In Fig. 1 the device will operate as an ordinary gas-cock; and by bringing the de-. vice into the position shown in Fig. 2, it acts as a pilot-light. By turning the screws 5, in or out, the amount of playpermitted the cock 6 is varied, and the size of the pilotlight varied accordingly. In fact, the two screws may be adjusted to different lengths, so that if the cock is turned in one direction, a certain amount of gas will pass, while when the cock isturned in the other direction more gas (or less gas) can pass. This provides slmultaneous variations for two different sized pilot-lights. But it is obvious that the set screws may be dispensed with entirely, in which case their place is taken by any projection that would limit the play of the nose 11 when in its upper position; or the barrel 2 with its flange 4 will be so shaped, as by giving an inclined face to the latter, as to produce the same effect.

Having thus described my invention, I claim:

1. The combination of a gas-fixture, a gas cook turning axially therein, a pivotallyadjustable stop carried by said cock, a-stationary stop on said fixture and located in the path of said stop in only one of the ad justments thereof, and a second stationary stop on said fixture and located out of the path of said stop in its first-named adjustment and in its path in the second adjust- ,ment thereof.

4. The combination With a gas-fixture, of

. a pair of oppositely-disposed and relativelystationary stops a second pair of oppositelydisposed and relatively-stationary stops, and a relatively movable stop that is adjustable to co-act at will with either member of one pair only of saidstationary stops to the exclusion of possible engagement with either member of the other pair and vice versa. 7

is adjustable to co-act with the wing to the exclusion of the set-screw and vice versa.

In testimony'whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE GILGHER.
